This is a stretch I randomly started doing a few weeks back that I really enjoy. It stretches your hip flexors and can be used as a pre-splits stretch. Basically, you find a high step, as shown, and place one foot on it. (I keep my foot slightly turned out for comfort reasons and because that’s how it has to be in ballet.) Keeping both hands on the step, slide your back foot out until the back leg is straight. You can try removing your hands from the step and extending the front leg more or bending into it to change up the stretch.
